Fatal error in internal_Init_thread: Other MPI error, error stack:

[js-jixu]

Hi, developers.

I installed moose on a cloud host. But moose can't run in parallel:

Fatal error in internal_Init_thread: Other MPI error, error stack:
internal_Init_thread(60)...........: MPI_Init_thread(argc=0x7fff718e6c6c, argv=0x7fff718e6c60, required=0, provided=0x7fff718e6c7c) failed

MPID_nem_tcp_get_business_card(397): 
GetSockInterfaceAddr(369)..........: gethostbyname failed, simple (errno 1)

The installation process looks very smooth, and there are no errors. What is the reason?

Hi, Guillaume.

I've read the troubleshooting page but failed to find related information about my problem. I can activate moose and run the input file in serial. But when I use mpiexec -n 2 ~/projects/.../opt -i , it encounters an error.

This virtual machine has previously installed openmc. When I use conda info -- envs to check the environment, it shows this:

And I've found that there is nothing in /root/mambaforge3/envs, while there is a moose folder in /root/mambaforge3/envs on my own PC's moose. Is it because I didn't install moose in the anaconda3 environment？

Did you search for gethostbyname on that page?
It s about modifying the hosts file

Your suggestion is very helpful and I can run it in parallel!
